the windows size of virtual box guest host always changing?

[nanjian5]

Hi all,

I want to know why the windows size of virtual box guest host is always changing?

I installed a XP guest on my XP system.
Then I find that the windows size of guest XP is changed to a smaller size when I double click a normal file folder.
It will restore to previous size when I double click again.

It also will happen when double click anything, or drag the left key of mouse.

Can anyone tell me how to fix it?

Thanks in advance.

I guess you are talking about your Windows XP guest. Which host (= machine, on where you execute VirtualBox) is that? If the VM window size changes, then the guest changed its screen resolution.
